That is fairly cute. I guess they had to avoid actually showing tech that they didn't have rights to or something because they could have easily shown how a normal person could become superman with existing tech.
There are exoskeletons, augmented reality, and adaptive armor that would be more impressive than "I have LEDs on my chest".
Not to mention the stuff going on in the DIY area (in the title!) where people are mounting flame throwers to their wrists, designing jet packs, etc.
A wonderful comic - I especially like the numerical factoids which connect the fantasy with reality. I can imagine it might actually capture the imagination of a young scientist - it certainly would have caught my eye.
